computeHpIC {PCAN} | R Documentation

## Compute Information Content (IC) for each HP based on genes by HP

### Description

Compute Information Content (IC) for each HP based on genes by HP

### Usage

    computeHpIC(content, hp.descendants)

### Arguments

`content` | a list providing the content associated to each HP
`hp.descendants` | a list providing for each HP all its descendant HP terms

### Details

This function assumes that all the HP terms taken into account belong to the same family of terms(i.e they are all descendants of the same term).

### Value

a vector of IC named with HP terms

### Examples
